چکیده
In this paper, we researched visualization of guided wave propagation in pipe with defect. The characteristic of three-dimensional sound field is simulated by finite element method. First, the characteristics of many modes of guided wave propagation in pipe and the interaction of guided wave with defect is studied. Then, the model of scattering sound field for defect exist is builded when guided wave propagation. The interaction of guided wave with defect is rebuilded by the model we build. At last, visualization process is simulated by building the model of pipe with defect and loading guided wave by using the soft of ANSYS. This research will make it easily to numerical and intuitionistic understand the location of defect and the characteristic of guide wave propagation in pipe. The research will make it easily to apply nondestructive testing technology in engineering based on guided wave.

متن کاملGuided Wave Propagation in Bend Pipes using Split Domain FEM Approach
Ultrasonic Guided Wave inspection of pipes has been extensively used in various industries such as oil, gas and petrochemical industries. The behavior of guided waves in straight pipes is well known but the presence of features like pipe bends, welds may distort the receiving signals. It is therefore a challenging task to study the behavior of guided waves through these features. However, the 3...

In this paper a space-averaged Navier–Stokes approach was deployed to simulate the wave propagation over coastal structures. The developed model is based on the smoothed particle hydrodynamic (SPH) method which is a pure Lagrangian approach and can handle large deformations of the free surface with high accuracy. In this study, the large eddy simulation (LES) turbulent model was coupled with th...
